Question

What is the slope of a line perpendicular to the line of the equation in the above ? Please help answer !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!!!!!!!

Answer 1

• - 4

Explanation:

• Slopes of perpendicular lines are negative-reciprocals.
• If m is the slope of one line, the slope of the perpendicular line is -1/m.

Let's find the slope of the given line:

• x - 4y = -12

Rewrite this in the slope-intercept form: y = mx + b

• x - 4y = -12
• 4y = x + 12
• y = 1/4x + 3

The slope is 1/4

The perpendicular line has slope

• - 1/(1/4) = - 4
